commit: 5a35435ef4e6e4bd2aabd6706b146b298a9cffe5 soc: fsl: qe: remove PPC32 dependency from CONFIG_QUICC_ENGINE
date: 6 months ago
config: arm64-randconfig-s031-20200527 (attached as .config)
compiler: aarch64-linux-gcc (GCC) 9.3.0
reproduce:
# apt-get install sparse
# sparse version: v0.6.1-240-gf0fe1cd9-dirty
git checkout 5a35435ef4e6e4bd2aabd6706b146b298a9cffe5
# save the attached .config to linux build tree
make W=1 C=1 ARCH=arm64 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
If you fix the issue, kindly add following tag as appropriate
